Question
From a pack of 52 cards, One card is drawn at
random. What is the probability that the card drawn is a queen or a heart?Solution
Sol. S= 52 cards There are 13 cards of heart (including one queen) and there are 3 more queens. Let E= event of getting queen or a heart. Then, n (E) = 13 + 3= 16 P (E) = [if gte msEquation 12]>
What value should come in place of the question mark (?) in the following question?
2000 ÷ 10 + 250 × 2 �...
1120 / √x = 80 Then x = ?
- What will come in place of (?), in the given expression.
144 ÷ √36 + 13² – 100 = ? Find the simplified value of the given expression:
(12 ÷ 3 of 2 + 11 of 2) ÷ 4
25% of 300 + √(?) = 35% of 600 - 15% of 300
45% of 1020 + ?% of 960 = 747
- What will come in the place of question mark (?) in the given expression?
121/? = ?/144 6% of 520 + 5% of 620 = ?
